PS4 constantly crashing after latest update

Adding my contribution to this topic, ever since the latest Iwo Jima update, the game seems problematic and I've never had this issue during the 2 weeks I was playing prior. At first I couldn't get past the main menu so I deleted the app and reinstalled. Now I can play games but at random, the game crashes and I get sent back to PS home. Sometimes I can play 2-3 games while other times I crash before the 1st one ends. I understand it is an outdated console generation but would greatly appreciate a fix.
